Title: Process for producing heavy soda from light soda
Inventor: FLORIN GERD
IPC: C01D7/37
Filed: 1983-04-19
Abstract: A process for producing heavy soda from light soda is proposed, whereby the heavy soda produced has a bulk density of at least 1000 g/l and is absolutely free of dust. The previously produced light soda (1) is first compacted mechanically (3) to give coarse scales or flakes which are then crushed mechanically (5); from this crushed product, the coarse grains, preferably greater than about 1.5 mm, which are undesired in the product, are then separated off; in a fluid-bed classifier, the fine-grain fractions up to about 0.15 mm out of the remaining grain fractions are classified away by means of an air stream and discharged with the exit air from the fluid-bed classifier in such a way that the grain fractions between about 0.15 and 0.4-0.5 mm, also present and to the greatest possible extent as in the crushed product, are retained in the grain spectrum of the product leaving the fluid-bed classifier (10), namely the heavy soda.   <IMAGE>

Title: Electromagnetically generated mechanical vibrations to loosen crowns
Inventor: SCHUBERT WERNER DR MED
IPC: A61C3/16
Filed: 1983-05-20
Abstract: Especially in conically distally tapering but otherwise solid hollow bodies (Fig. 1), electromagnetically generated mechanical vibrations can be directed in reversal of the bell mouth function, bundled to the distal part of the hollow body and transmitted from there with much higher energy to other bodies such as crowns. A very outstanding property of such mechanical vibrations is to bring about loosening at interfaces. Using the above-mentioned, conical hollow device according to Claim 1-7 this physical property was utilized for loosening bridges, crowns and the like in a way better than with the customary, purely mechanical devices, and this may also be useful for extraction of teeth. <IMAGE>

Title: Coin selector/counter
Inventor: MATSUSHITA HIDEAKI
IPC: G07D5/00
Filed: 1983-07-14
Abstract: A coin selector/counter designed to differentiate and count coins according to their face values often has to process not only the admissible, that is to say statutory, coins, but also misshapen coins, counterfeit coins, foreign coins and the like. Such coins should be separated out with a high degree of reliability. When the operation of selecting/counting the coins is stopped after a predetermined number of coins, subsequent coins have to be removed from a passage of the machine. The invention meets this need by retaining an inadmissible coin on the passage when such an inadmissible coin is detected. The coins are thereafter removed automatically and returned into a funnel of the machine.

Title: Test point switch
Inventor: EICHHORN WALTER
IPC: G01R27/26
Filed: 1984-04-21
Abstract: A test point switch for automatically measuring capacitance in objects (1) under test such as circuit boards and hybrid circuits must themselves have a low capacitance for measuring very low capacitances. For this purpose, all lines and components carrying the measurement signal are thoroughly shielded with the aid of an earth line (M). The measurement is taken via a capacitance measuring device (2), two measurement paths (H, L) and single-pole, mercury-wetted reed relays (R1...R16). A connector strip (S2) shielded on all sides, which is connected to the relay via shielded lines (F1...F8), is provided for connecting the object (1) under test. Since the measurement paths (H, L) are in each case arranged spatially separate in the upper and respectively lower region of a circuit board, mutual capacitive influencing of the measurement paths is prevented. The relays are driven from an input device (3) via converters (U1, U2) and relay drivers (T1, T2). <IMAGE>

Title: Flexible connection for hot-running lines
Inventor: SUDMANNS HANS
IPC: F01N13/18
Filed: 1984-05-12
Abstract: Joints in exhaust lines of internal combustion engines are bridged by flexible connections. A socket (13) with spherical annular flanges (10, 19) arranged on its ends is slideably mounted in recesses of the line ends (11, 12). The socket (13) is lined with a protective sleeve (14) forming an annular gap (53). Delayed heating of the socket (13) compared to an unprotected design is thereby achieved during running up of the internal combustion engine. The rate of heating of the socket (13) and the line ends (11, 12) are approximated to one another to such an extent that the corresponding diameters expand evenly when heated. Plastic deformation of the spherical annular flanges (19, 20) is thereby avoided. <IMAGE>

Title: Detonation safety device
Inventor: FUERST WILHELM
IPC: F42C15/21
Filed: 1984-05-19
Abstract: A detonation safety device (11) having a detonator safety slide (25) and having an impeller-driven generator (21) which can be extended out of a projectile (12), transversely with respect to the longitudinal axis of said projectile (12), is intended to be designed in such a manner that disturbances relating to the operation of the impeller-driven generator (21) and relating to the flight dynamics of the projectile (12) during a first stabilisation flight phase are avoided as far as possible. For this purpose, at a suitable time after firing the projectile (12), the safety-position lock of the impeller-driven generator (21) is released by means of an electrical control circuit (42), after which the impeller-driven generator (21), which is extended out of the projectile (12) at the side, supplies the electrical power for releasing the lock of the detonator slide (25); however, the latter can be displaced into its armed position only when a blocking device (31) has already been removed from the slide sliding guide (24), because the blocking pin probe end (33) is no longer held firmly by a structural element which is adjacent to the projectile (12) before firing. A bend (38) on the blocking device (31) engages behind the detonator slide (25) when this locking pin (26) should already be drawn on the basis of incorrect operation, before the displacement enable is provided by the blocking device (31), in order in consequence, for safety reasons, finally to suppress the possibility of displacement of the detonator slide (25) into its armed position in this case. <IMAGE>

Title: Laser interferometric angle-measuring instrument
Inventor: SCHUESSLER HANS-H DR ING
IPC: G01B11/26
Filed: 1984-05-22
Abstract: The invention relates to a laser interferometric angle measuring instrument having a laser head and a polarisation beam-splitter arrangement, as well as a sine bar, arranged on the measurement object, having two triple reflectors which are arranged thereon at a defined spacing and to which in each case the two separate beams of the interferometer arrangement can be applied. In order to increase the measurement accuracy, the polarisation beam-splitter arrangement is constructed symmetrically, so that the two beam components have mirror-image courses and the same length of travel. As a result, it is also possible to enlarge the width base and to increase the accuracy of resolution without impairing the measurement accuracy.

Title: Bead package exhaust gas catalyst
Inventor: VESTER GERHARD
IPC: F01N13/02
Filed: 1984-10-04
Abstract: A bead package exhaust gas catalyst for the catalytic purification of exhaust gas for motor vehicles, combustion power stations, heating units in industry and homes. In the known exhaust gas catalysts, in particular for motor vehicles, the ceramic tube used as the catalyst support structure is the weak point. In the bead package exhaust gas catalyst, the catalyst substance, or the support structure on which the catalyst is applied, has the form of small beads. A multiplicity of these small beads are introduced into the exhaust gas stream closely and tightly packed into a bead package - held together in a net or by sieves, gratings, or the like.   The advantages achieved by the invention are, in particular, that the bead package exhaust gas catalyst     - is more favourable in terms of costs in manufacture,   - has a higher degree of efficiency,   - reduces the costs of the "purification",   - prolongs the functionality and service life, - when noble metals are used as catalyst, reduces the costs of recovery of these noble metals from the spent catalysts, - makes possible the use of the considerably cheaper phthalocyanins and other catalyst substances,   - and reduces the temperature.   In particular, for the use of readily volatile catalyst substances, such as for example phthalocyanins, the invention provides the successive connection of two or more bead package exhaust gas catalysts, which mutually ...

Title: Galvanic element with a polymeric electrode
Inventor: BITTIHN RAINER DIPL PHYS
IPC: H01M4/137
Filed: 1984-11-29
Abstract: A suitable deposition support for electrochemical polymerisation deposition of the electrode-active organic material 4 and for the further use as an electrode support and discharge is aluminium 1 retaining its natural oxide skin 2, if the aluminium is provided with an electron-conductive coating 3 of, for example, Au, Pt, Ni or C. Above a certain potential gradient between the layers 1 and 3, electrons, by means of a tunnel effect, can overcome the oxide barrier 5 and flow out via the aluminium discharge 1. When pickled, the aluminium can also serve as the immediate deposition substrate. If the aluminium is used in the form of a net or metal mesh, the metal and polymer are bonded particularly firmly, and the mesh cavity can be used for incorporating the amount of electrolyte required for charging the polymer electrode, as a result of which a thinner separator is sufficient as an electrolyte reservoir, by means of which the cells achieve an even more favourable power density. <IMAGE>
